I think it was more than community hype. Sean, for whatever reason, made claims that turned out to be objectively false.

you are right about a lot of the claims seeming to be straight up BS, but it was all understandable imo. people had unrealistic expectations because the devs didn't take care to manage them well.
there are space battles, and there are things you could call factions and economy, they are just woefully underpar compared to expectation and marketting material.
